Parallel cluster computing projects use a large number of commodity PCs to provide cost-e ective computational power to run parallel applications. Because properly load-balanced distributed parallel applications tend to send messages synchronously, minimizing blocking is as crucial a requirement for the network fabric as are those of high bandwidth and low latency. We consider the selection of ...

We propose a novel photon number resolving detector structure with large dynamic range. It consists of the series connection of N superconducting nanowires, each connected in parallel to an integrated resistor. Photon absorption in a wire switches its current to the parallel resistor producing a voltage pulse and the sum of these voltages is measured at the output. The combination of this struc...

We study the process of diffusive conduction that we use in our optoelectronic switches to achieve rapid optical switching on a picosecond time scale . We present the characteristic Green’s function of the diffusive conduction derived for arbitrary initial conditions. We also report the series solutions of the diffusive conduction obtained for different boundary conditions V=0 and V=0 along the...

An active-clamping quad-flyback converter is proposed to achieve zero voltage switching (ZVS) for all power switches. The secondary sides of quad-flyback converter are connected in parallel to share the load current. Thus, the transformer copper losses and the conduction losses on the output diodes are reduced. Activeclamping part including one auxiliary switch and one clamp capacitor can relea...

We recently succeeded in producing nanostructures made of RNA-protein (RNP) complexes. We show that RNA and the ribosomal protein L7Ae can form a triangular-like nanostructure that consists of three L7Ae proteins, which form the apices of the triangle, bound to one RNA scaffold. This shape is created through a 60° kink introduced into the RNA structure on L7Ae binding. By varying the size of th...

Software-Defined Networking (SDN) allows control applications to install fine-grained forwarding policies in the underlying switches, using a standard API like OpenFlow. Highspeed Ternary Content Addressable Memory (TCAM) allows hardware switches to store these rules and perform a parallel lookup to quickly identify the highest-priority match for each packet. While TCAM enables fast lookups wit...

to be dropped by the TCP layer of the end systems. The redundant packets in the retransmitted segments clog the network switches and thus exagerating the congestion and further packet loss. In distributed computing environment that involves high-volume data transfers, it is very important to minimize packet loss at intermediate switches/routers by maximizing the utilization of memory resources ...
